Hmm, the filesystem went down...

...and I think this is complaining about this debugging test in
iomap_page_release:
WARN_ON_ONCE(bitmap_full(iop->uptodate, nr_blocks) !=
folio_test_uptodate(folio));
which checks that we're not releasing or invalidating a page that's
partially uptodate on a blocksize < pagesize filesystem (or so I gather
from "POWER10 LPAR" (64k pages?) and "XFS" (4k blocks?))...

...aha! The filesystem has gone down (hence the metadata IO errors at
the top of the report) during generic/475, which is a test that
exercises filesystem crash recovery. It simulates a crash by calling
EXT4_IOC_SHUTDOWN and unmounting.
Given that in this case we've already cleared SB_ACTIVE from the
superblock s_flags, I wonder if we could amend that code to read:
if (inode->i_sb->s_flags & SB_ACTIVE)
WARN_ON_ONCE(bitmap_full(iop->uptodate, nr_blocks) !=
folio_test_uptodate(folio));
Since we don't really care about memory pages that aren't fully up to
date if we're in the midst of freeing all the incore filesystem state.
Thoughts?

Ooh, nice! :)

It's been there since the start of fs/iomap, so bisecting wouldn't help
much anyway.
